Back when In-N-Out opened in Meridian in December, "In-N-Out Mania" swept the Treasure Valley. Even if you go today, expect to wait in line... the people of Idaho sure do love their In-N-Out burgers.

Boise's New In-N-Out Update

The road to Boise's new In-N-Out began with taking down the old Pier 1 the week of January 25th. It was the end of an era for the Boise Towne Square Mall.

Since then, excitement has been building for the California-based burger chain's expansion in the Treasure Valley. While their location in Twin Falls was denied, Nampa will be getting its very own In-N-Out at the old TGI Fridays making Nampa In-N-Out's third location in the Treasure Valley.

In-N-Out is notoriously secretive about opening dates and we didn't learn of Meridian's official grand opening until the day before.

So, when will Boise's new In-N-Out open?

While it's just a guess, we can reference what we witnessed with Idaho's first In-N-Out to help us make an educated guess - emphasis on "guess."

Based on what we know, construction of Meridian's In-N-Out initially began on May 27, 2023. In-N-Out in Meridian officially opened its doors to the public on December 12th later that year.

That means it took about 199 days for In-N-Out to go from hammers and nails to burgers and fries. If we used that same time frame on Boise's location, that would put In-N-Out's forecasted opening on Sunday, August 11th - or perhaps that weekend, Friday, August 9th.

Of course - this is all an estimation and we're fully aware there are other factors that could affect the timeline.

Until then, we were able to get a look at the latest construction progress.

Take a look and let us know - when do you think In-N-Out is opening its doors?
